Brushed aluminum table lamp with pebble switch by Walter and Moretti 1970

Superb table lamp by walter and brushed aluminum moretti from the 1970s. The special feature of this lamp is that it consists of a single piece of aluminum and is equipped with a wireless gas pebble-shaped switch (the lamp only lights up if the pebble is positioned in a specific location). Classic bib socket, bulb not provided. Signature of the designers under the base. The lamp is in perfect working condition. It has some marks of time (slight stitches, micro-scratches, blackening under the blind) but no major defect.
